ZOYENERA KUYAMBA KWAMBIRI PA CHIwonetsero 1383
16-BIT DELTA SIGMA ADC NDI I2C INTERFACE
LTC2451
DESCRIPTION
Demonstration circuit 1383 imakhala ndi LTC2451, 16 bit high performance analog-to-digital converter (ADC) yokhala ndi mawonekedwe a I2C. Kulowetsako ndi bipolar ndi mitundu yosiyanasiyana ya Ref-to Ref+. Mwiniwake wa modulator sampling njira yochepetsera kuyika kwapakati pakali pano kukhala yochepera 50nA magnitude kutsika kuposa ma ADC a delta sigma. LTC2451 imapezeka mu ma pin 8, 3x2mm DFN phukusi ndipo ili ndi mawonekedwe osavuta kugwiritsa ntchito I2C.
DC1383 ndi membala wa gulu la ziwonetsero la Linear Technology's Quick Eval™. Lapangidwa kuti lilole kuwunika kosavuta kwa LTC2451 ndipo litha kulumikizidwa mwachindunji ndi ma analogi a pulogalamu yomwe mukufuna kugwiritsa ntchito pogwiritsira ntchito bolodi ya DC590 USB Serial Controller ndi mapulogalamu operekedwa kuti ayese ntchito. Maulendo apamtunda owonekera amalola kukhazikika koyenera kwa ma prototype circuitry. Pambuyo powunika ndi pulogalamu ya Linear Technology, ma siginecha a digito amatha kulumikizidwa ndi purosesa / chowongolera cha pulogalamu yomaliza kuti mupange mawonekedwe a serial.
Kupanga files za board board izi zilipo. Imbani fakitale ya LTC.
LTC ndi chizindikiro cha Linear Technology Corporation
Chithunzi 1. Kukonzekera koyenera kwa Zida Zoyezera
DZIWANI IZI
Lumikizani ku DC590 USB Serial Controller pogwiritsa ntchito chingwe cholumikizira 14 choperekedwa. Lumikizani DC590 kuti mulandire PC ndi chingwe cha USB A/B. Yambitsani pulogalamu yowunika yomwe yaperekedwa ndi DC590 kapena dawunilodi kuchokera http://www.linear.com/software.
Pulogalamu yolondola idzaikidwa yokha. Dinani batani la COLLECT kuti muyambe kuwerenga voltage. Tsatanetsatane wa mawonekedwe a mapulogalamu alembedwa mu menyu yothandizira gulu lowongolera. Zida zilipo zodula mitengo, kusintha voltage, kusintha chiwerengero cha mfundo mu mzere tchati ndi histogram, ndi kusintha chiwerengero cha mfundo avareji kwa chiwonetsero cha DVM.
Chithunzi 2. Chithunzi cha Mapulogalamu
KUKHALA KWA ZINTHU ZOFUNIKA
KULUMIKIZANA NDI DC590 SERIAL WOLAMULIRA
J1 ndiye cholumikizira champhamvu ndi digito.
Lumikizani kwa DC590 serial controller yokhala ndi 14 kondakitala chingwe choperekedwa.
LUMPERS
JP1 - Sankhani gwero la REF +, mwina LT66605 kapena kuchokera kunja komwe kulumikizidwa ndi positi ya Ref + turret.
ZOKHUDZA ANALOG
Kulumikizana kwa ma sign a analogi kumapangidwa kudzera pamzere wa turret nsanamira m'mphepete mwa bolodi. Komanso, polumikiza bolodi ku dera lomwe lilipo ndege zapansi zowonekera m'mphepete mwa bolodi zingagwiritsidwe ntchito kupanga mgwirizano wolimba pakati pa malo.
GND - Turret iyi imalumikizidwa mwachindunji ndi ndege zapansi zamkati.
VCC - Ili ndiye gawo loperekera ndi zolozeratagndi ADC. Osatengera mphamvu iliyonse pamfundoyi.
Vin- Uku ndiye kulowetsa kwa ADC
